Effect of temperature on the components and content of aromatic substances in ‘Purple Ruffles’ Ocimum basilicum leaves

Potted ‘Purple Ruffles’ Ocimum basilicum plants were treated with different temperatures; the components and relative content of the leaf aromatic substances were then analyzed using SPME and GC-MS. A total of 55 compounds were detected in the leaves of ‘Purple Ruffles’ O. basilicum at different temperatures; linalool was the main aromatic component of the leaves. The components and relative content of aromatic substances differed among the different temperature treatments. We concluded that 15℃ (day/night, 20℃/10℃) is the ideal growth temperature for extracting aromatic components from the leaves of ‘Purple Ruffles’ O. basilicum.
